About Dots and Boxes

Dots and Boxes is a classic pencil-and-paper game that has entertained players for over a century. Also known as "Squares," "Paddocks," or "Dots and Dashes," this deceptively simple game hides surprising strategic depth that continues to challenge players and mathematicians alike.

The game was first described in the 19th century and became popular as a quick, portable game that only requires a pencil and paper. Players take turns drawing lines between adjacent dots, and the player who draws the fourth side of a box captures it and scores a point.

What makes Dots and Boxes fascinating is the "chain" strategy - understanding how to force your opponent to give you multiple boxes in a row. This strategic element transforms a children's game into a challenging puzzle that rewards careful planning.

How to Play Dots and Boxes

1

Draw a Line

Click on the space between any two adjacent dots to draw a horizontal or vertical line. Lines are permanent once drawn.

2

Complete Boxes

When you draw the fourth side of a 1x1 box, you capture that box! It fills with your color and you score a point.

3

Bonus Turns

Completing a box gives you another turn immediately. Skilled players can capture multiple boxes in a single turn!

4

Win the Game

The game ends when all boxes are captured. The player with the most boxes wins!

Dots and Boxes Tips & Strategies

  • 1.Avoid the third side: Never draw the third side of a box unless necessary - you're giving your opponent a free point!
  • 2.Think in chains: Connected boxes form chains. The player who takes the first box in a chain usually gets them all.
  • 3.Sacrifice small chains: Sometimes it's smart to give away 2 boxes to gain control of a larger chain of 6 or more.
  • 4.Count ahead: In the endgame, count the total boxes in each chain to plan who will capture what.
  • 5.Control the center: Early in the game, avoid creating opportunities near the center where chains can grow large.

Frequently Asked Questions About Dots and Boxes

Dots and Boxes is a classic pencil-and-paper game for two players. Players take turns drawing lines between adjacent dots. When a player completes the fourth side of a box, they claim that box and get to play again. The player with the most boxes at the end wins!
Click on the space between two dots to draw a line. When you complete a box by drawing its fourth side, the box becomes yours (shown in your color) and you get another turn. The game ends when all boxes are claimed, and the player with the most boxes wins.
Key strategies include: 1) Avoid drawing the third side of a box (giving your opponent a free box), 2) Create 'chains' of boxes that force your opponent to give you multiple boxes, 3) Count boxes carefully in the endgame, and 4) Sometimes sacrificing a small chain gives you control of a larger one.
When you draw the fourth and final side of a box, that box is captured and marked with your color. You also earn a point and get to take another turn immediately. This can lead to chain reactions where you capture multiple boxes in one turn!
Chains occur when boxes are connected in a line. If your opponent must give you the first box in a chain, you can take all boxes in that chain. Advanced players aim to create an odd number of chains to ensure they take more boxes overall.
For small boards, Dots and Boxes is mathematically solved. On larger boards, while perfect play is computationally complex, experienced players can use chain theory and other strategies to play at a very high level.
A 4x4 or 5x5 box grid (5x5 or 6x6 dots) is ideal for beginners. It's small enough to finish quickly but large enough to allow interesting strategic play. Our game uses a 5x5 box grid.
On a 5x5 grid with 25 boxes, a tie is impossible since the total is odd. However, on even-numbered grids, ties are possible if both players capture equal numbers of boxes.

History of Dots and Boxes

Dots and Boxes has been played for well over 100 years, with the earliest known description appearing in the 1889 edition of "La Science Illustrée" by French mathematician Édouard Lucas. The game quickly spread as a popular pastime that required nothing more than paper and pencil.

In the 20th century, mathematicians began seriously analyzing the game. The "chain rule" strategy was developed, revealing that behind its simple exterior lies a game of considerable mathematical depth. Computer scientists have since proven optimal strategies for various board sizes.

Today, Dots and Boxes remains popular in classrooms, on paper during boring meetings, and now online. Its combination of accessibility and depth ensures it will continue to entertain players for generations to come.
